The Portwest PS13 Mega KN Safety Glasses are half-frame safety glasses with two lenses and a co-injected TPE browguard. The browguard adds protection from particles, impact and glare above the lenses.
The side arms extend and tilt, so you can set the length and lens angle to suit your face. Soft rubber temple tips help the glasses stay put as you move. Both lenses carry high-level anti-scratch and anti-fog coatings to help keep your view clear.
